Paten ed March 2a, 1900.

Appllottlon filed August 0, mos. was my. 441,253.

Be it known that 1, Penn? S. Knsrnn, a citizen of I the United States of. America; residing. in the city of Bridgeport, inthe county of Fairfield, in the State of C0nnectiout, have invented a certain new anduseful Improved Inclosed- Fuse, of which the ,fol-

' lowing is a specification.-

' The object of my invention is to so'construct an inclosed fuse for electrical protect- "ivje purposes .that all soldering operations n senibled in t may be completed before the partshreasto%ether in the finished product;

n. the accompanying drawings Figuie '1 is a perspective view illustrating arts before being assembled; Fig.- 2- is a ongitudinal sectionalview of the endof an inclosed fuse in accordance with my invention; Fig. 3 is in a plane perpendicular to the section Fig. 2, that is on the line 33, Fig. 4; Fig. 4 is an end view; Fig. 5" is a cross section on the line 55, Fig. 2.

In the: accompanying drawings, I have fuse of t type in which the exterior conshown mnvent1on as applied to an lnclosed tact men] ers are in the form of blades projecting' from the ends of the inclosed fuse, in

\ stood that the-opposite end may be conopening in the cap and headed screwspassing a plane parallel with the axis of the fuse cartridge, and in the views I have illustrated only one end of the fuse, but it will be understructed in the same manner.

A is the tubular inclosing-casing of hard j vulcanized fiber or other suitable insulating the passage throug 0 case, but at the same time the :parts shall be secured firmly and rigidly l" two subscribing witnesses;

provided with slots 6; for

and solder or other suitable means to an end plate D. The rods R to which the fuse links are connected by solder or otherwise are m'echanicall secured and soldered to the 'inner face 0 each end plate D, the outer face of whiehlisadapted to bear a ainst the inner face of the corresponding cap v Each plate D is provided with two threaded holes d, d, for the reception of the threaded ends of headed securing screws 7, 7, whichare inserted from the outside of the cap through rovided for the purpose, so asteholcs, 8, 8, drawthe the parts l1oles.9 are formed in each cap to serve as vents. 1.

By the above described construction, all the soldering of the parts together can be effected for both ends of the fuse (the links ates firmly up to their ca s after as; liave been assembled. Ad itional to the'rods, the latter to the wid'plates and the blades to'the latter) before the parts are assembled, and then it is only-necessary to pass the-caps over the blades and over the ends of the inclosin casing, and then by the screws 7, 7, draw tie'parts firmly together and further secure the caps to the casing by the screwsb.

I claim as m' invention An inclosed use,-having a tubular casing and a metallic cap to close'thc end thereofv end plate to which the links suith an internal are electrically connected, a blade secured to the end plate and projecting through iv an through holes in the end of the cap into the end plate to draw the latter firmly up to the inner face of the ca In testimony wliereof I have name-to this specification, in the signed my presence of PHILIPZS.
